If you are in or near Interlaken, make sure you take some time to visit Trummelbach falls. What you might read about in guide books doesn't even come close to the experience of visiting. I had never seen anything like it; the power and noise of the water is completely humbling. We visited on a grey and rainy day, so while the views on our walk weren't great, the falls weren't affected by the bad weather. It is not to be missed!
